【摘要】 针对医学模拟教学和微创手术技能培训开发了虚拟腹部微创手术操作平台,可非常逼真地描绘腹部微创手术的真实环境并符合医学基本伦理,能够模拟常用手术器械和腹腔内器官组织,实现人机实时交互。平台分为硬件设计和软件设计两大部分。硬件设计包括主控制器、数据采集单元和操作平台结构单元。硬件部分主要负责数据采集及处理。软件设计包括主机单元、几何建模单元和碰撞检测单元。软件部分主要负责手术器械和器官以及病例的选择、几何建模,包括常用手术器械,例如手术剪刀、手术钳以及腹腔内器官组织。实验结果证明,虚拟腹部微创手术操作平台适用于高校的医学教学和医疗机构人员的培训,能提高我国医学模拟教学水平并与国际接轨。更多还原

【Abstract】 A virtual platform for minimally invasive abdominal surgery has been developed for medical simulation teaching and training of minimally invasive surgical skills.The platform can describe realistic environment of minimally invasive abdominal surgery and accord with basic medical ethics.It can also simulate commonly used surgical instruments as well as intra-abdominal organs organization,achieving real-time human-computer interactions.The platform is divided into two parts,i.e.,hardware design and software design.The hardware design consists of a main controller,a data acquisition unit and an operating platform structure unit.The hardware part is mainly responsible for data acquisition and processing.The software design consists of a host unit,a geometric modeling unit and a collision detection unit.The software part is mainly responsible for choices of the major organs and surgical instruments and cases,and geometric modeling which includes surgical instruments,such as surgical scissors,forceps as well as intra-abdominal organs organization.Experimental results show that the virtual platform for minimally invasive abdominal surgery is suitable for teaching in medical universities and medical personnel training,and can improve China’s medical simulation teaching standards to reach international levels.更多还原
